I built a free, open-source web app that turns any old device into a 100% private security camera. No uploads, no installation.

I built Vigilo, a web app that turns your old phone or laptop into a motion-detecting security camera.

The main feature: it’s 100% private.

• It runs entirely in your browser.
• All motion detection happens on your device. Your images never leave your hardware.
• No uploads, no tracking, no installation (it’s a PWA).
• It sends motion alerts directly to your Telegram.

Try it: vigilo.eifr.xyz

Code: github.com/eifr/Vigilo

I’d love to get your thoughts on this “privacy-first” approach to DIY security.
